Pul-e-Khumri-Chimtala Transmission Line

POWER completed the Pul-e-Khumri to Chimtala transmission upgrade study. The project is being accomplished for the US government and involves the necessary system studies to determine the electrical viability of importing 450 MW to the Afghanistan power system from Uzbekistan and Tajikistan. The present transmission line is double-circuit 220 kV and approximately 202 Km in length. Study results will include an assessment of the possibility of a re-conductor of the transmission line and employing the use of series/shunt capacitors and static VAr compensators (SVCs).

POWER also performed an engineering study of reactive power compensation (RPC) to optimize the 220-kV transmission line section from Pul-e-Khumri to Chimtala. This includes automation of existing RPC and description of improvements necessary to increase the Chimtala substation transformer capacity by 160 MVA. POWER developed a technical scope of work with supporting documents for engineering and procurement of RPC equipment. The client will receive a final report, including locations and sizes of RPC to be installed, as well as technical specifications, general arrangement drawings, scope-of-work packages, and recommended evaluation criteria for project execution.
